The purpose of a receiver

[Jetfun]

Could someone please enlighten me, on what the advantage of having more receivers around than we already have? I mean, if we can follow any plane today, from a to b, what advantage would it be to have more?
Just trying to learn.
If theres a good thread already about it, feel free to link to it.
Cheers

More receivers will give better coverage at low level, military helicopters for instance flying around 500 to 1000ft would need receivers quite close to give good tracking

I see, i just never experienced a loss of any aircraft ive been following, but i guess it happens now and then.
